To all whom it may concern.'

Be it known that I, JULIUs SINGER, a citizen.` of the United States, residing 4at Racine, in the county of Racine. and State of Wisconsin, have invented certain new ,and useful Improvements in Ash-Sitters;

andi do declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in ing operation but permitted to open to dump the cinders, and means for permitting the.-

-neciprocation vot the sitter inthe ash com-- ypertinent but preventing its beingpnshedjdumping position except by the express in-l telit of the operator. Y Another' object is to provide a sitter of this character which will be comparatively simple, strong, durable and. inexpensive in construction, eficient and reliable in operation "and in which the dust arising from. the sifting of the `ashes will befcntirely com A fined in the casing.

0f construction, and the combination and arg' rangement of parts as 'will be more fully described and claimed.

y In the accompanying drawin is a side view of my improve Fig. 2 is Figure 1 ash sitter; en end view thereof; Fig. 3 is a section taken on the line 3--3 of Fig'. 4; Fig. 4v is a vertical l tudinal secy tion taken on the line 3- and sition .for

sifting the ashes therein; Fig.` isa similarview showing the position of the screen -when discharging the cinders therefrom.;

Fig. is a vertical sectional View taken onf the line (3-6 of Fig. 4; Fig. .7 is a similar` View taken on the line 7-7'of Fig. 4; 8 isa detail perspective vicwfof the sifting screen. L

'My improved ash sitter coiripdi'ses a Casin -1 which may be of any suitablgsi'ze or shape" and which is constructed of. ID.Btal or other .are adapted to be .o to beplaced-in the sifting screen of the device.

A1-The remaining plo't'onof 'the casing is compartment andv into..-

jthe ashes or cinders 6v bin the lower portion `of compartments g3g-and 4. Secured? to the inner surfaces of With these and other obyectsm view, the invention consists of certain novel features.

'shown at 13.

fire-proof n'iatcrial. ln the lower portion of the casing 1, Vwhich is here shown as being of rectangular oblong shape, is arranged a central transversely disposed vertical partition 2 which divides said lower portion of the casing into'ylan ash ,compartment 3 Aand a cinder compartment 4. Slidablymounted in the bottom of the ash compartment 3 is ash receiving drawer 5 while .in the bottom of the compartment 4 drawer 6. The drawers and 6. are adapted to be drawn from and,- inserted into their respective compartments through suitable openingsv in` one side .of the ,casing l aas shown.

On the top of the casing l above the ash comparti'nent 3 .is an upwardly projecting extensiony 7 `the upper"end .ot whiclris closed by suitablyhinged doers B ,as clearlyshown .in Figs. 4 and of the drawing Whichfdoors period to permit thevv ashes tightly-closed on .its iupper end by 'a top 9. -Secured ,to one end of :theash compartment d and to the partition 2 are downwardly and inwardly projecting -deiiecting plates 10, while in .the cinder compartment 4, are'similarly arranged cinder detiecting `.plates 11. The plates 10 4and '11 are .provided todefiect into thedrawers 5 and the sides ofthe casing above the ash compartment 3 are angle Iron tracks 12 which -froin lsaid partition extend downwardly at an angle into the cinder compartment 4 as lThe Adownwardly inclined endsof the tracks 12 preferably correspond with and are secured to the adjacent deflect- .ing late ll-in this compartment. Arranged 1n t the compartments 3 and 4 and extending therethrough the entire length ofthe casing are screen supporting rods 14 one of which is disposed adjacent -to each` side of the casing is a cinder receiving e upper portion of the casing above l :and have their ends firmly secured in any .i

'suitable manner tothe ends of the casing as shown.

7. Slidablll SUPPOIIedA-GD thel rods 14 is a sifting screen l5 com frame 16 having oh sides'eyes 17 whichI sldqbly engage the' rods 14 and thus support: the screen frame. Hinged at 1d to the innler end of the fname -ising a rectangular "los upper edge of its 16 is a screen bottom 18 of wire netting or other foraminous material which when in an operative position is engaged with the lower edge of the frame as clearly shown in Fig; 4 of the drawings. Arrangedl` below and secured to the screen bottom 18 -is an ash receiving and guiding chute or tray 19 the bottom of which inclines from the outer toward the inner end of the screen frame as shown. When thus arranged the chute or tray 19 receives the ashes as they pass throughthe yscreen bottom 18 and discharge said ashes out through the inner orrear open end of the chute from whence the ashes fall into the compartment 3 and are directed by the deflecting lates 10` in the ash receivingdrawer 5. 'F with a suitable agitating rod or handle 20 which hasits inner end secured in any suitable manner to the inner end of the screen frame 16 and which projects and works' through an opening 21 in one end of the easing 1 above the ash compartment 3 therein.y

In the upper side of the inner portion of the handle 20 is a recess 22 or said inner end of the handle may be reduced to form a stop shoulder 23 which when the'handle is reciprocatedfor agitating the screen is adapted t` be brought into engagement with ay dctent 24 in the form of a short dat plate pivoted at one end to the end of the casing adjacent to one side of the opening 21 through which the handle operates. In the lower edgeot the plate 24 is a notch 25 which whenv the detent is swung downwardly to an operative position engages the recessed or reducedv portion 22 of the handle and thereby reduces the size of the openings 20 so that when the handle is pushed inwardly the shoulder 23 will come into engagement with the detent which will thus limit the inward movement of the screen or prevent the inner end of the latterfrom beingl projected beyond the partition 2 forming one end of the ashvcompartment 8. Bythus limiting the inward movement of the screen it will be seen that the ashes are prevented., from being discharged into the cinder compartment as the ashes in falling through the screen bottom' 18 are caught by the chute or trayv 1 9 and discharged" from the open end thereof into the compartment 3 in the manner described.

By providing the tray or chute 19 Vand ar-l rangingzthe same 'as herein shown 1t 'will be seentha-tjthe reciprocating movement of' the screen is :increased to substantially the length of the screen -franle or in other words thel screen may be projected over the cinder compartment for a dist-ance equal to uearliv the length of the screen frame without danger of the ashes lall-i-ngintothe lcinder compartment. By rigidly securing the ash chute 19 to the seinen, the 'latter when located over he screen 15 :is provided the einder chute will`be in position to prf*- vent any ashes that may be located within the chute carried by the screen from being dumped with the cinders.

When the sifting operation is completed and it is desired to discharge the sifted cnders into the drawers e of the cinder compartment 4, the detent 24 is swung upwardly thus permitting the larger part of the handle 20 to pass through the opening 21 whereby the screen may befurther projected to a position over the center of the cindcr compartment in which position the screen bottom will leave the straight portion of the track 12 and will follow the downwardly inclined portion 13 thereof, thus causing said bottom to swing downwardly on its hinge connection with the inner end of the screenframe as clearly indicated 1n Figo or the drawings, thus discharging the cinders from the screen into the drawer 6. As soon as the handle is again pulled outwardly and the screen frame thus retracted the engagement of the bottom 18 with the inclined portion 13 of the track will gradually swing the'bottom 18 upwardly into a closed position against the lower edge of the frame 16 in which position the screen will be held by the straight portion of the tracks 12 on which the side edges of the bottom slide. In order to cause the bottom to slide ".reely on the tracks 12, I preferably providethe side edges oi. the bottom with ball bearing casters 2G which slidably engage the tracks 12 as shown. These casters (of which several are shown along the bottom in Fig. 5 although they might be reduced in number to a pair at the outer ends of said bottom) travel on thel tracks or rails 12 as the sifter is reciprocated and hold the screen bottom and its chute closed against the lower edge of the frame until the latter is pushed over the partition 2, so that no ashes or dust can escape until the screen 15 falls open as Iseen in F ig. 5. By this construction the depth of vthe ash compartment can be reduced because in reciprocating the screen along the tracks it can be moved as far as possible so long` as the casters hold its bottom closed.

By constructing my improved sifter as herein shown and described it will be seen that-the sifting operation may be performed and the siftcd cinders discharged from the sifting screenwithout opening the casinef` thus providing a positively dust proof. sitter. It willi'also he noted that the opening and closing of the bottom of the screen for the discharge of the cinders is entirely automatic.

From the foregoing description taken in connection with'ihe accompanying drawings, the construction and operation of the invention will he readily understood with out requiring a more extended explanation.

Various changes1 in the torni, proportion and the minor detailsof construction may be resorted to Without departing from the principle or sacricin any of the advanta-gesofi the invention as c aimed. I'

Having thus described my I claim is: l

Inl an ash sifter,'the combination With a casing having a transversev partition produing cinder and ash compartments, of tracks secured to the opposite sides of said casing `along the full length of tfhe ash compartment vand bent downwardly at an angle over the partition and projecting into the cinder compartment2 supporting guide invention, what* rods extending the-full. length of the casing and disposed above said tracks and in horizonte-l alineme'nt therewith, a screen frame slidably yarranged with said rods and tracks,

.a hinged bottom for' said screen frame, an

chute-carried by t e screen ere held there# .in while the cinders ere being .dum ed, and

means for reclprocatlng the screen rame.

In testimony .whereof I have hereunto` set my'hand in presence of two subscribing witnesses.; n
